There have been endless debates about which types of power amp are best. Heavy ones or lightweight ones? Black ones or grey ones? The $299 ones or the $1299 ones? Can you hear the difference in a live situation? Probably not. My advice is to spend an amount of money on it that you are comfortable with and buy a brand that you have heard of before. I have used Peavey, Crown, Mackie, Stewart and QSC, and guess what? They all worked. Good luck.
